R. ANSCHTZ TYPEWRITING CALCULATING MACHINE 10 sheets-sheet 1o Filed April 30, 1941 Hll-I Patented June 26, 1945 frrrnizvviarrmo cALcULA'rING MACHINE Robert Anschtz, Zella-Mehlis, Germany; vested inthe Alien Property Custodian lApplication April 30, 1941, Serial No. 391,202 l In Germany May 15, 1940 This invention relates to typewriting-calculatwhich is equal to a step of travel of the paperr carriage, and so located between the denominational wheels of the accumulator, 1 as to point H the amount registered on the wheels.

When, in the step by step travel 'of the accumulator and its master vactuator relatively tov each other, one of these punctuation places is brought "into the adding Zone, that is to say, positioned in registry with the master actuator as a result of the usual step movement of the carriage, it has been" customary to provide'means for automatically tripping the'carriage escapement mechanism tol eiiect a second immediately successive 'step of movement of the carriage for the purpose of. bringing the wheel of nextlower denomination and the master actuator-into registry.

Accumulators vor registers, the denominational wheels of which are arranged seriatim with no intervening punctuation or pointing'off spaces are well known, but where it is desired to associate an accumulator having punctuation spacing with a register not so provided, both mechanisms being under control of the paper carriage for the simultaneous entry or withdrawal of digits on the wheels of corresponding denominations in the respective mechanisms, gross inaccuracies would occur unless provision is made-to compensate for the extra spacing occurring as a result of the comma-skipping of the carriage vin relation tothe accumulator.

One object of the present invention is to provide'a novel means forcoordinating a non-punctuated set of denominational 'elements to a punctuated set of denominational elements, whereby to f 'enable the proper denominational digits of an amount tobe simultaneously entered or withdrawn' on the corresponding denominational elements of both the punctuated and the non-punctuated sets. y

To-this end I contrive to' offset the effect of theextrafstep of movement of the paper carriage' past the punctuation space, by providing what may be called a limited lost motion connection between the carriage and the set of nonpunctuated denominational elements, which results in a non-transference of motion to the actuator for the non-punctuated set, ,during the vsecond step of movement of the carriage.

Other objects and advantages will ybe referred to in the following specification, and particularly pointed out in the claims.

GENERAL DESCRIPTION The present device according to the invention is for use on a typewriting-calculating machine having an automatic total-taking device, which besides the conventional state control (addition, subtraction) is also equipped for multiplication. A multiplying mechanism i (Fig. 3) suitable for forming the product from two factor values is preferably mounted on theleft beside the machine frame 2. The factor values are suitably entered order by order in the denominational gear systems provided for this purpose within said multiplying mechanism I (multiplicand gear 3 and multiplicator gear 4) by way of the conventional calculating keys 5 (Fig. l) depressed during normal calculations (addition and subtraction) and by means of the customary totaltaking control device (not shown).

The entry order by order of the factor values into the multiplying mechanism I (Fig.l3) and after their product has been computed, the removal of the product value from the multiplying mechanism I, is effected by way of a registering wheel 6 (Figs. 2. 3, 8). The latter is mounted to slide but not to revolve on a shaft 1 driven by the total-taking control mechanism of the typewriting-calculating machine and is moved step by step by the mechanism according to the invention under control of the paper carriage movement with respect to the gear wheel of one of the series of gears 3 or 4 (Figs. 8 and 3) corresponding to the decimal order selected during the tabulating of the paper carriage 8. The gear system 3 consists of eight wheels arranged in parallel by decimals by means of which any desired multiplicator is entered by decimals into the multiplying mechanism.

The dein'ce according to the invention is arranged as follows:

Arrangement o-f the coupling device As is known, in order to limit a left-hand movement of the paper carriage 8 which has been started by depressing the respective tabulator key of a decimal tajbulator keyboard 9 (Fig. l), corresponding tabulator riders are set on a tabulator rider bar IIl (Figs. 2 to 4) arranged at the rear of the paper carriage 8. A similar tabulator rider is also set on the rider bar IU, opposite the column totalizer I2 intended for storing the multiplicand value, in such a position relatively to the totalizer that as soon as the carriage shifts the column totalizer I2 to locate its comma position K (Fig. 10) into operating position opposite the master wheely the rider I I by its lug I 54 (Fig. 4) will positively release the paper carriage 8 to move one step towards the left so that automatic skipping of the comma is effected. A similar rider I3 is mounted to the left, as viewed from the front of the machine, of the tabulator rider II at a distance marked c in Fig. 10. The distance marked a which is limited on one side by the driving or master gear A of the calculating mechanism of the machine and on the other side by the highest calculating order wheel of the column totalizer I2 storing the multiplicand, corresponds to the distance b extending from the point M of the multiplying device controlling the multiplication to the highest order ofthe multiplicand gear system 3. It should be noted, however, that the latter rider I3 does not cooperate with the decimal tabulatordevice of the typewriting-calculating machine.

A coupling hook I4 is screwed to said rider I3 by means of a screw I3a (Fig. 4). This hook I4 at its upwardly and rearwardly bent portion is recessed to provide a coupling shoulder I5 as well as a second coupling shoulder I6 which is offset towards right the length of one step of the paper carriage. The shoulder I5 during the tabulating into the operating position of one of the calculating orders of the column totalizer I2 to the left of the comma position K engages a lug I1 of a pawl I 8 whereas this lug I1 of the pawl I8 is engaged by the coupling face I6 of the coupling hook I4 during the comma skip, and as the calculating places of the column totalizer I2 to the right of the comma position K are moved into operating position.

Opposite the column totalizer I9 for storing the multiplier, another tabulator rider 2D (Fig. 3) corresponding to the rider II is set on the tabulator rider bar Ill in such a position relatively to totalizer I9 that as soon as the comma position of the totalizer moves into operating position, the rider 2D with its lug 26a will positively start a shifting step of the paper carriage 8 towards left for the purpose of automatically skipping the comma position. A notched coupling hook 22 is iixedly screwed to this tabulator rider 20 at 2| in such a way that its coupling shoulders 23 and 24 can also cooperate with the lug I1 of pawl I8. The pawl I8 (Figs. 3 to 5) is mounted to swing on a projection 26 of a slide 21 by a screw 25. The slide 21 is mounted to slide horizontally on a U- shaped supporting bridge 28. For this purpose a headed screw 29 screwed into the supporting bridge 28 projects through a longitudinal slot 30 of the slide 21 and another headed screw 32 screwed into a supporting member 3| (Fig. 3) extends through a second longitudinal slot 33 of the slide 21. Preferably the slide 21 comprises two parts which can be adjusted by means of screwslot connections 34, 35 to form an integral unit. One end of a tension spring 31 is fastened to a pin 36 riveted in the slide 21. The opposite end of said spring is hooked in a suspension bar 38 which is fastened to the supporting bridge 28. This spring`31 constantly tends to move the slide 21 towards the right (arrow 39) which movement ment of the locking pawl 46.

is limited by the right hand end 48 (Figs. 3 and 4) of slide 21 striking against a rubber stop 4I. The cushioned stop 4I is fastened in a metal box 42 which, by means of screws 44 protruding through its downward extended arm 43, is screwed to the supporting bridge 28. This bridge is itself mounted on the rear supporting bar 2a of the machine frame 2 at 28a. A locking pawl 46 is mounted to swing on the right hand arm of the above-mentioned pawl I8 (Figs. 3 and 5) at 45. The locking pawl 46 supports one arm of a torsion spring 41 coiled around a screw 48 threaded into the pawl I8 and constantly tending to move the pawl 45 anticlockwise around the pivot 45. When the slide 21 is in normal position, however, (Figs. 4 and 5), a pin 48 riveted into the locking pawl 46 is supported by a bevel 5I) of a control member 5I thus preventing any further move- When, however. this locking 49, 50 is released, as will be described later, the torsion spring 41 moves the locking pawl 46 anticlockwise around the riveted pin 45 so that the front edge 46a of the pawl 46 will strike against a stop pin 52 riveted into the slide 21. In this position the locking pawl 46 by means of its slanted edge 53 can cooperate with one of the chamfered edges |4a or 22a of the coupling riders I4 or 22. The control member 5| vis screwed to the supporting bridge 284 at 54.

The right hand end 55 of the locking 'pawl 46 is shaped like a hook to which the longer arm 56 of a torsion spring 51 is connected. The torsion spring 51, which is coiledaround a screw 58 threaded into the slide 21 with its short arm projecting into a bore-hole of the slide 21, tends to move the locking pawl 46 anticlockwise around the riveted pin 45. Owing to the lock 49l 50, pawl 46 cannot normally participate in this movement, so that the tendency of the torsion spring 51 will be transferred tothe pawl I8 by'way of the rivet connection 45, causing ,the pawl to swing anticlockwise around the screw 25 until in its rest position the right-hand arm of the pawl I8v by its rear edge 60 strikes against a pin 6| fastened in the slide 21.

The pawl I8 also has a slanting eclge 62 which when entering the multiplicand. at the moment of skipping the comma position K (Figs. 11 and 13) provided in the column totalizer I2 storing the multiplicand, cooperates with a pin 63 (Figs. 4 and 5) and, after the entry of the multiplicand has been completed, with a pin 64, which pins are relatively offset and depend from a supporting member 66 screwed to the supporting bridge 28 at 65 and overhanging the path ofthe shoulder 62. The pins are spaced from each other by the distance of two steps. Whenentering the multiplier, the slanting shoulder 62 of the pa'wl I8, at the moment of skipping the comma position provided in the column totalizer |9 storing the multiplier, engages a pin 61, and after the entry of the multiplier has been completed it engages, a pin 68. These pins 61 and 68 are arrangedin the same manner as the pins f63 and 64 but depend from a swinging flap 69, the pins 61 and 68 whilst the flapis in normal position. lying outside of the pathway of the shoulder 62 of the pawl I8, as willy be hereinafter explained. The flap 69 is fastened on a shaft 1 I as at 10 and said shaft 1| is mounted to revolve in two supports 12 and 13 fastened on the supporting bridge 28. A depending crank 15 is also rigidly mounted on the shaft 1| by a hub 14. A spring suspension pin 16 is riveted to said crank 15, and engaged by one end of a spring 11-whose opposite end is suspended from a pin 18 vfastened in the suD- porting bridge 28, the spring influencing the 96 is mounted for adjustment by means of screws 91 on the tabulator rider 99 set on the tabulator bar opposite the column totalizer 98 storing the product on another tabulatoi` rider |00.

Arrangement of the sethg mechanism for the registration wheel 6 -fastened to the upper end of a shaftl |06 (Figs. 2,

3 and 9), mounted to rotatein the supporting member 3| previously mentioned which is screwed members 15, 1| and 69 in the direction of arrow f a hub 84 and is constantly influenced around the shaft 1| `in the opposite direction of arrow 19 by the above-mentioned tension spring 9|` until in the resi', position its face 85 strikes against the pin 16. The locking lever 82 is also provided with a locking catch 86 which at the right moment is capable of cooperating with the right hand edge 81 of a lug 88 mounted on the slide 21.

A rail 90 is screwed on the flap 69 at 89 (Fig. 4.), This bar 90 is bent upwards at its front part to provide a cam surface 9|, a horizontal surface 92 and another cam surface 93. surfaces 9|, 92, 93 of the rail 90 can cooperate with a roller 94 (Figs. 2 to 4) mounted to revolve on the upper end of a supporting bracket 96by means of a rivet 95 (Fig. 4). The said bracket These control to the rear supporting bar 2a of the machine frame 2 at |01. At the lower end of shaft |06` (Figs. 2,3, 8 and 9) a cog wheel |09 with e. g. 20 teeth isrigidly mounted by a sleeve |08. Said toothed wheel I 09 is in mesh with a rack ||0 screwed on the slanted part of a slide referred to henceforth as sliding carriage I I I. By means of theheaded screws ||2 (Fig. 8), the heads-of which move in guide slots I|3 of a rectangular bar 4, the sliding carriage is mounted .to slide on the bar I I4, in horizontal direction. Y The bar ||4 is fastened to the rear section of the frame I6 containing the multiplying mechanism, by'screws II5.

A U-shaped setting member ||8 (Fig. 9) is also fastened to the sliding carriage I at I I1 (Fig. 8) which by means of bore holes I9 (Fig. 8) drilled in its arms encircles lwith little play the shaft 1 wheel M controlling the multiplication proper, l

and mounted to the left of the multiplier train of wheels 4.

The individual toothedwheels of the gear systems 3 and 4 are loosely mounted to turnsideby side on a shaft I2| fixed in the frame IIS of the multiplying mechanism I by means of their hubs |20 (Fig. 3). Consequently, the abutting ends of said hubs |20 of the adjoining gears will rub against each other so that it might be possible for the adjoining wheels to the left and to the right of one particular wheel in the train of wheels 3 and 4 to rotate with the driven gear so that `certain values are registered unintentionally. In order to avoid such faulty registrations, the following device has been provided.

Device for preventing the frictional turning of wheels adjoining the wheel io be revolved within the train of wheels 3 and 4 whilstits other arm rests on the catch pawl |25.

The coil spring |21 tends to move the catch pawl |25 constantly anticlockwise around the screw |24 (Fig. 8) 'until in the rest position a bent lug |30 of the pawl |25 contacts the upper edge |3| of the supporting member |23. The catch pawl |25 (Figs. 8 and 8a) carries a laterally projecting flange |32 having two catch teeth |33 and |34 which enter between the teeth of those gears of the gear system 3 and 4 which adjoin the particular gear in mesh with the registering wheel 6.

The catch pawl |25 is also provided with a forwardly extending arm |35, the upper edge |36 of which is in slight Contact with a bar |31 (Figs. 3 and 8') mounted at the left in a lever |38 (Figs.

3 and 8) and at the right in a lever |39. Both levers |38 and |39 are fastened rigidly on a shaft |42 rotate in the supporting ears |40 and |.4I of the frame IIB. The lever |38 (Figs. 2, 3 and 8) has a laterally extending pin |43 and the lever |39 has a similar pin |44 which pins protrude through curved longitudinal slots |45 of the levers |46 and |41 mounted on a shaft |48 supported in the frame II6. The shaft |48 and the levers |46 and |41 can be moved clockwise (Fig. 8) by suitable means, not Shown when depressing an operating key R (Fig. 1), whereby the multiplying process, that is, the calculating of the product, is started. If this is the case, the pinslot connections |45, |43 and |45, |44 as Well as the members |31, |38, |39 and |42 are likewise moved clockwise (Figs. 2 and 8) around the pivots |40, I4I. Simultaneously the bar |31 acts upon the edge |36 (Fig. 8a) of the arm |35 of the catch pawl |25, moving the latter against the coil spring |21 clockwise around the screw |24. Accordingly,

the catch teeth |33 and |34 of the catch pawl |25 move out of the teeth of adjacent gears of the gear systems 3 or 4, just locked by them, so that these toothed wheels are released for rotation. This is necessary since when calculating the product, the individual wheels of the gear systems 3 and 4 are revolved simultaneously more or less by means of their respective racks B, (Figs. 8 and 10) not explained in detail.

When the operating key (R), which starts the multiplication, is not depressed, the above-mentioned members remain in their normal positions, Fig. 8, so that those toothed wheels of the gear systems 3 or 4, respectively, which are located to the right and left of the toothed wheel in mesh with the registering wheel 6, are prevented from turning.

OPERATING METHOD or THE COUPLING DEVICE` Entering of the multz'plz'cand The method of operating the device according to the invention will be explained for better understanding by way of a simple multiplication chosen at random, as follows:

It should be noted that in the following the order to the left of `the comma `will be referred to as"units order and the orders to' the right of the comma as "tenths or hundredths orders.

First, the conventional preparations are made for performing bookkeeping operations on the typewriting-calculating machine and the paper carriage 8 is brought into its extreme right hand position. Then a vpreparatory key V (Fig. 1) is depressed, whereby the typewriting-calculating machine is set for multiplication.

By depressing the key corresponding to the units order of the decimal tabulator keyboard 9, the paper carriage 8 with its column totalizers |2 mounted thereon, is shifted leftwardly in any conventional manner until arrested when the units order of the appropriate column totalizer is in operative relation with the master gear A (Fig. 11) in which the multiplicand value 3,25 is to be stored.

With reference to the amount 3,25 it is to be understood that the term units order relates to the units of dollarsl order, rather than the units of cents order which is regarded as the hundredth order.

During this movement towards the left of the paper carriage, the coupling element I4 in the position of the paper carriage shown in Fig. 10 with its coupling edge I5 engages the hook I1 of the pawl I8 so that the coupling members I8, 21, 46, (Figs. 4, 5) thereby participate in the further movement of the paper carriage towards the left. At the beginning of the movement of the members |8, 21, 46, etc., the pin 49 of the locking pawl 46 escapes from the oblique edge 50 of the control member 5|. Consequently the locking pawl 46 is turned anticlockwise around its pivot 45 by the spring 41 and then lies with its front edge 46a against the pin 52. Simultaneously the locking pawl 46 in this position comes to lie with its edge 53 against the edge I 4a (Fig. 6) of the coupling element I4. In this way a safe coupling connection between the rider I3 and the coupling members I8, 21, 46 is established in both directions of movement of the carriage.

During the leftward movement of the coupling members I8, 21, 46, the spring 31 (Fig. 3) is tensioned. Simultaneously by means of the rack I 04 (Figs. 3 and 9) of the slide 21 the. toothed wheel |05 in mesh with the said rack as well as the shaft |06 and the toothed wheel |09 mounted on same are revolved anticlockwise (arrow a). The latter moves the rack I|0 with which it is in mesh and thereby also the sliding carriage I|| (Fig. 9) towards the right (direction of arrow 39) opposite to the direction of the tabulating movement of the paper carriage 8, whilst the headed screws |I2 (Fig. 8) screwed into the same slide in the guide slots I|3 (Fig. 9) of the angular rai1 ||4.

It will be noted that owing to the different numbers of teeth of the toothed `wheels |05 and |03, the extent of movement of the sliding carriage III is greater than that of the paper carriage 8.

The setting member II8 with the registering wheel 6 participates in the movement towards the right of the sliding carriage I I I. That particular tooth of the registering wheel 6 which happens to lie in line with interdental spaces of the single gears of the gear systems 4 and 3 consequently slides past the toothed wheels of the multiplier gear system 4 and then past the higher denominational orders located to the left of the unitsorders of the multiplicand gear 3 and nally at the end of its rightward movement, meshes with the units-gear E of the multiplicand gear 3 (Fig. 1l). At this moment the tabulating movement towards left of the paper carriage 8 as well as the movement towards left of the coupling members I8, 21, 46, |04, the movement of the members |05, |06, |09 in the direction of the arrow a and the movement towards right of the members I 0, III, I|8 and 6 are iinished. Consequently the units-orders of the column totalizer I2 and the registering wheel 6 are now in operating position, the latter being opposite the units-place E of the multiplicand gear 3.

The supporting member |23 (Fig. 8a), and therewith the catch pawl |25 also participated in the movement towards right of the setting for the column totalizer I2, is closed.

member |I8. .At the end of the vtabulating and setting movement of the members III, ||8 and 6, as shown in Fig. 11, the left tooth 133 (Fig. 8a right) of the catch pawl |25 now meshes the multiplicand gear 3. Consequently, the adjoining gears to the right and 'left of the units gear E 'of the gear system 3 are locked against any revolving movement and therefore cannot participate inv any turning of the units wheel E. The tabulating and setting movement of the paper carriage 8 and the registering wheel 6 iinished, the calculating key marked 3 o the calculating keyboard 5 (Fig. 1) is depressed to register the 3 of the multiplicand 3,25. Consequently the conventional column totalizer mechanism of the machine is started, andthe coupling |50, |5I (Fig. 3) between the registering wheel shaft 1 and the differential shaft |52 Then the known column totalizer shaft |52 is turned automatically by three units in the direction ofthe arrow |53. The shaft I1 (Fig. 8) and `the registering wheel 6 also participate in this movement by means of the locked coupling |50, |5I. Since the registering wheel is in mesh with the units wheel E of the gear system 3, as mentioned above, the units wheel E is likewise positively turned `by three units in the direction of arrow |53a. This driving movement is now transferred by the units wheel E, of the gear system 3 to the corresponding rack of the rack and gear system B of the multiplying mechanism.

Simultaneously with the registration of the "3 of the multiplicand value 3,25 in the multiplying mechanism, a 3 is also registered additively in the units dollars order of the column totalizer I2 and the type-lever of the figure 3 is positively made to write upon the booking sheet directed around the platen of the/ paper carriage 8. The return of the type-lever then releases the carriage escapement device so that the paper carriage 8 under the influence of a carriage feeding mechanism, moves one shifting step to the left. v

Owing to the coupling connection I4, I5, I1 (Fig. 11), I8, 46, the. coupling 2 1, |04 (Fig. 3) are also positively moved towards the left a further shifting step against the spring 31. Thereby the shaft |06 by means of the gears |04,

|05 is moved further in the direction of arrow a, and consequently the sliding carriage III by means of the gears |09, I|0, and also the setting member ||8, the registering wheel 6 as wellas the catch pawl |25'by the member |23 (Fig. 8a) are moved towards the right by one step (direction of arrow 39). The registering wheel 6 there.- by comes into mesh with the tenths wheel Zt 4 of the train of wheels 3 (Fig. 12).

Shortly before completion of this movement of the coupling members I8, 21, 46 vby one step towards left, the edge 62 (Fig. 4) of the pawl I8, contacts with the pin 63 of the supporting member 66. Consequently, duringI the subsequent slight leftward movement 'of the members I8, 21, 46 until the completion of this one step movement, the pawl I8. and the pawl 46 are slightly moved clockwise around the pivot screw 25 against the spring 51, the coupling members I8,

21, 46 assuming the. positions with respect to the member I4, as shown in Fig. 12. The distance covered by the pawl I8 in this case will only be a short one, so that the coupling connection I5, I1 for the time being remains intact. The shifting step of the paper carriage towards left justV described caused the comma position of the column totalizer I2 to be moved into operative position. As mentioned previously, the tabulator and comma rider II (Figs. 4 and 12) is located opposite this calculating place on the tabulator rail I0 and its catch |54 at this m0- ment operates a distance skipping device, the just completed step to the left of the paper carriage 8 thus being succeeded by a further shifting step towards left by automatic and positive action. The coupling connection I5, I1, will, of course, impart to they coupling members a still further movement towards the left. At the beginning, of the latter movement, the oblique shoulder 62v of the pawl I8 slides farther along the pin 63 of the supporting member 66. Consequently also pawl I8 and pawl 46 are moved farther around the pivot screw 25 against the spring 51. In doing so, the catch I1 of the pawl I8 slides olf the edge I5 of the coupling element I4, so that the coupling connection I5, I1 for the coupling members is interrupted. At this moment the spring 31, which has previously been tensioned, takes eiTect and causes the coupling members 21, I8, 46 to be moved towards the right in the direction of the arrow 39.

Meanwhile the shifting step towards left (comma skipping) of the paper carriage 8 which, as previously mentioned, has been initiated by the catch |54 of the rider II takes place, so that now the paper carriage and the coupling members shift in opposite directions instead of traveling together. Such relative movement between the coupling numbers I8, 21, 46 and the coupling element I3, 4 is arrested by contact of the coupling hook |1 with the shouldered face I6 of the coupling element, at the end of one letter or denominational space, the hook 'I1 clinging to the face I6 (Fig. 13) It follows that the coupling members I8, 21, 46 and the driven members |04, |06, |I0, III, 6 (Fig. 3) mutually compensate for the comma skipping of the paper carriage 8, so that the registering wheel 6 is moved by only onestep or letter space, whilst the paper carriage 8 and its column totalizers jump by twosteps or letter spaces from the units of dollars order of the column totalizer |2 across the comma place into the tenths place. This is done for the reason that, as known, no comma or vacant places have been provided in the multiplying mechanism in order to save space.

These operations completed, the tenths order of the` column totalizer I2 as Well as the tenths order ZT of ,the multiplicand 'gear system 3 are in their operating positions (Fig. 13).

Now the calculating key 2 of the calculating keyboard 5 (Fig. 1) is depressed in order to enter the 2 lof the value 3,25, whereupon the gear of the tenths place ZTv (Fig. 13) of the gearsystem 3 and the corresponding rack of the rack system B as well as the tenths wheel of the column totalizer I2 are advanced two steps and the type lever carrying the 2 is caused to print on the sheet carried by the platen. The subsequent return movement of the type lever releases the carriage for another letter space movementV towards the left. Owing to the coupling connection I6,-I1 (Fig. 13), the coupling members I8, 21, 46 participate'in this leftward movement. Simultaneously the horizontal rear edge 62a (Fig. 13) ol the pawl I8 slides along the pin 63, but this movement is not imparted to the pawl I8 itself.

Owing to the continued leftward movement of the coupling members I8, 21, 46, the sliding carriage III, by means of the gear train |04 (Figs. 3 and 9), |05, |106, |09, IIO, and the registering wheel 6 as well as the catch members |23, |25, are moved towards the right (direction of arrow 39) another denominational step which locates the hundredths order of the column totalizer I2 in operating position and the registering wheel 6 in mesh with the hundredths gear Ht of the multiplicand train of wheels 3. In this position'of parts, the strip-01T edge 62 of the pawl I8 engages from the right with the second strip-off pin 64 of the supporting member 66.

v Now the key of the calculating keyboard 5 (Fig. 1) corresponding to the value "5 is depressed in `order to enter the 5 of the multiplicand 3,25, whereby said value is entered into the hundredths order Ht (Fig. 3) of the multiplicand gear set 3 and the gear and rack system B, as well as into the hundredths order of the column totalizer I2, and the type lever corresponding to 5 is actuated.

The return type lever on its return releases the paper carriage for another letter spacer movement again and simultaneously, the coupling members I8, 21, 46 are likewise carried along towards left by the coupling connection I6, I1 (Figs. 3, 4 yand 13). Consequently the oblique shoulder 62 of the pawl I8 slides past the pin 64 of the supporting member 66 whereby pawl I8 and pawl 46 are swung farther clockwise (Fig. 3) around the pivot screw 25 against the spring 51 (Fig. 4) whereupon the incline I1 of the pawl I8 clears the yface IB -of the coupling element I4, so that the coupling system is set free. Through the action of the tensioned spring 31 (Fig. 3) the coupling members I8, 21, 46 at this moment are jerked smartly towards the right (direction of arrow 39) into their initial positions in accordance with Figs. 3 and 4, the right end 40 of the slide 21 striking against the sound deadening rubber stop 4| to,arrest the parts. At the beginning of the movement of the members I8, 21, 46 towards the right, the rear edge 62a of the incline 62 of the pawl I8 slides off the pin 64, whereupon the pawl I8 and pawl 46 are moved anticlockwise around the pivot 25 by the spring 51. The movement of said pawl I8 is halted in the rest position by the rear edge or tail 60 striking against the pin 6| and the movement of the said pawl 46 is halted by the front edge 46a striking against the pin 52. vThe pawl 46 is again swung out clockwise against the spring 41 around the rivet pin 45 shortly before reaching the right end-position of the coupling system I8, 21, 46 by action of pin 49 sliding along the incline 50 of the control member 5| (Fig. 5) to locate the pawl 46 with its control or locking edge 53 outside of the path of movement of the coupling element 22 positioned on the bar I in the plane of the column totalizer I9 in which the multiplier is registered, whilstvthe pawl I0 with its bill I1 extends into the pathway of the catch 23 of the coupling element 22.

During the return movement of the coupling system I8, 21, 46 into rest position, simultaneously the sliding carriage III by means of the racks and gears |04, |05, |06, |09, I|0 and the registering wheel 6, and the latch member |23, |25 are returned into the rest position towards the left,

according to Fig. 3. In this position the registering wheel 6 is in mesh with the wheel M pertaining neither to the gear set 3 nor to the gear set 4.

Entering of the multiplier After the multiplicand 3,25 has been registered in the multiplying mechanism of the bookkeeping machine in the above-described manner, that is, in the corresponding decimal orders of both the gear set 3 land the rack system B and stored in the column totalizer I2, the operator of the machine can write any desired text in the space between the column totalizer I2 'and `the column totalizer I9, by operating the keyboard 5 (Fig. 1). Then he depresses the units-tabulator key of the decimal tabulator keyboard 9, in order to enter the multiplier 1,40, whereby another leftward tabulating movement of the paper carriage results. During this movement, the coupling element 22 (Fig. 14) of the tabulator rider 20, having been set on the tabulator rail I0 opposite the column totalizer I9 in which the multiplier is to be registered, engages its catch 23 with the hook I1 of the pawl I8 and carries the coupling system I8, 21, 46 along towards the left tensioning the spring 31. The pawl 46 with its pin 49 now leaves the control member 50 and moving anticlockwise around the pivot against the spring 41, positions its edge 53 against the face 22a, of the coupling element 22, thereby ensuring the driving connection 23, I1 for entering the multiplier in the set of gears 4 (Fig. 14). It will be noted that the driving connection 23, I1 for entering the multiplier is established at a later moment than is the driving connection I5, I1 (Fig. 10) for entering the multiplicand in the tabulating motion, the delay being deiined by the distance marked a (Fig. 10), since the coupling hook 22 is secured directly on the tabulator and comma rider 20 for the column totalizer I9 and the registering wheel I5` does not have so far t0 travel, to engage the selected denominational gear of the gear set 4 corresponding with the digit of highest denominational value. The additional advance of the carriage through the distance a was necessary, since the registering wheel 6 had to cover the additional distance C corresponding to the width of the multiplier Value.

Owing to this leitward sliding movement of the coupling system I8, 21, 46 (Fig. 14), the carriage III, by means of the gear train |04 (Figs. 3 and 9), |05, |06, |09, IIO, and the registering wheel 6 as well as the locking members |23, |25, are simultaneously moved towards the right to position the registering wheel 6 with the units wheel e of the multiplier gear set 4 (Fig. 14). At this moment the tabulating movement of the paper carriage 8 is completed and simultaneously the units wheel of the column totalizer I9 has been moved into its operating position.

Whilst the units wheel is moving into its operating position, the roller 94 (Figs. 2 to 5 and 14) of the supporting member 96, moves with the paper carriage 8 and simultaneously acts upon the cam surfaceSI of rail of nap 69 to rock the latter as well as the members 82 and 15 against action of spring 11 and in the opposite direction to the arrow 19 around the bearing brackets 12 and 13. Consequently the pins 61 and 68 of the nap 69 are moved into the pathway ofthe shoulder 62 of the pawl I8.

The tabulating process completed, the key marked "1 of the calculating keyboard 5 is depressed in order to enter the "1 of the multiplier 1,40. Thus the l by means of the differential shaft I52, gearsv IIJ`,`cl,utch'I5I, registering wheel shaft 1 and the registering wheel 6 is entered into the units-wheel e (Fig. 14) of the gear set- 4.and yby-means ofthe corresponding rack of the rack system B is entered into the oorresponding order ofa multiplying mechanism C not explained in 'detailwhich is arrangedbeside the product mechanism P after the product gears Chave been broughtfto mesh with the rack system 3. 'Ihevalue l is also entered into the unitswheel `of the column totalizer I9 and lby means of thel corresponding type lever is typed upon the sheet ontheplaten;` The type lever on its return then initiates the unusual escapement to feed oi' the paper carriage il one step and the carriage, because of the coupling Connection 23, Il, ad- Vances the coupling'system I8, 2l, 46 one step to the left and hence, shift the registering wheel I5 one step' towards right (Fig. l5)- by means of the 'IMQ-"Inti, |05, IHS, Il'ii, III, II8,`-to1position the said wheel 6 'in' meshwith the tenths gear Zt of the multiplier gear set t.

Duringv the leftward step of the coupling systern` I8, 2l, '46, the cam shoulder 62 of the pawl I8 contacts the -pin El of the ldap (i9, whereby the pawls I8 and 45 against the'action of spring 51 arernoved slightly clockwise around thewpivot screw-25 but the coupling connection 23, II,lis still maintained." f* f The paper carriage, as it escaped yone stepinitiated by the return of the type lever, also caused the comma place of the columntotalizer I@ to shoulder 62 of the pawl I8 slides off the pin 6l of the flap 69, whereby the pawls I8 and 46 are moved clockwise around the pivot against the spring 5l and consequently the hook Il or"- the O-type lever is moved initiating further leftward step of the paper carriage 8 as wellv as of the coupling system'y I8, 21, 46. 'Simultaneously the slanting cam B2 Aof the pawl I8 slides along the second pin 68 of the flap 69, whereby the pawls I8vand 46 are moved fartherclockwi'se around the screw' 25 against the spring 5l and vconsetmently the hook I 'lof the pawl I8 leaves the recessed face 24 of the coupling member 22. The movement towards. left ofthe coupling` system having tensioned the spring 31, the coupling members I8, 21, 46 now tend to move vtowards right again whilst the registering wheel 6 on the shaft'l slides towards left under control of thegear' train Illd, M5, IB, I09, III,`IiI, II- (Figs. Band 9).`

As soon as `the hook I'I of the pawl I8 has been moved out ofthe path of the coupling member 22, the pawls I8 and '45 are restored bythe spring 5l to their normal positionsk (Figs..3 to 5).

The movement of the coupling system I8, `27, 46 vtowards the right (direction of arrow 39) and the movement of the sliding carriage III and the registering wheel 6 towards left is limited in that moment in which the registering wheel 6 is in mesh Withthe respective gear of the gear system 4`corresponding to the tens position Z (Fig. 17). This limitation takes places as follows:

Setting of the coupling system during total-takingy y of the product When tabulating the column totalizer IQ'intoi operative position-as already explained above@ the flap 69 and the shaft 'II as well asits lever I5 lare rocked clockwise by the roller 94' (Fig. 4)i of the supporting bracket or member 96 against the action of spring 'I'I inthe opposite direction of arrow 19. This rocking movement --is transmittingto the locking lever 82 by the spring link connection '16, 8I, 83` (Fig. 5) to contact'the stop arm 8'6 of the lockingylever 82 with the upper surface of the supporting bridge 28 (Fig. 17).

pawll I8` clears the face 23l of the vcoupling element 22 and after a one step relative vmovement between the coupling mechanisms between the catch I8 and the carriage connects with the reduced face 24 (Fig. 16) which is set back the distance of one letter space from the face 23. Consequently the paper carriage 8 advances two steps, whilst the registering wheel 5 is moved onestop only, so that now the tenths wheel of the column totalizer I9 is moved into operativeposition` and -theregistering wheel vEi is in mesh with the tenths wheel Z'I of the gear set 5. l Y

In ordertoenter the 4 of the multiplier value 1,40, the particular key corresponding to the gure 4 on the calculating` keyboard v5 (Fig. 13) is depressed, whereby the "4 is entered into the tenths gear yZt (Fig. 16) of the multiplier gears 4 which gear is driven as explained above.l Simultaneously the "4 by means or" the corresponding rack of the 'rack system. B is also entered into the proper order wheel of the multiplying mechanism Cas well as into vtlfievtenths wheel of the column totalizer I9, and is printed on the sheet held in the paper carriage. The subsequent step of the paper carriage 8 and of the coupling system (I8,

21, 46) then moves the registering wheel 6 into mesh Iwith the hundredths wheel Ht of the gear system 4 as thehundredths wheel of the column totalizer I9l is positioned into voperative position. In this position .the particular key of thecalculating keyboard 5 corresponding to "0 is depressed, 'whereby no value is entered but the In the example under consideration, the hundredths digit of the multiplier (l,40)"has'been entered in-'the machine, and printed,the usual escapement advances the paper carriage one step, as a result of Which-the coupling system I8, 2l, 45 is automatically Areieased from the coupling member 24, and the coupling system is moved towardsthe right by the spring 3l until, the right side edge'l of the projection 83 ofthe slide 21 contacts with theleft side surface ofthe locking stop arm 35 of the locking lever 82 in order `to check this movement. In this position, as illustrated in Fig. 17, the registering wheel is now in mesh with the tens gear Z of the gear system 4, the reason for which will be hereinafter explained: Y

The shifting step ofthe paper carriage `following the typing of the 0 of the multiplier 1,40 moves the column totalizery I9 into operative position with respect-to its right control position. Inthis position a comma'rider is suitably placed on the tabulator bar I0, which at this moment by means of its nose 'operates the distance skipping device of the machine, so that the paper carriage 8 is shifted by one further step. Consequently, after registering the hundredths digit of the multiplier value, the paper carriage is moved automatically two steps towards the left, the column totalizer 98, which later on receives the product, shifting therewith to mesh its highest calculating order wheel (Fig. 1'7) with the master Wheel A, The coupling system is not changed thereby in any way since the coupling connection has been disestablished as explained.

Now the result key R (Fig. 1) of the bookkeeping machine is depressed, whereby the product of the two factors, 3,25X1,40 that is 4,5500 is automatically calculated in the product mechanism P (Fig.,17) of the multiplying mechanism which does not belong to the invention and. therefore, is not shown. Simultaneously the multiplying mechanism automatically starts operation of the total taking mechanism of the bookkeeping machine, not shown. The totaltaking from the product mechanism in the present case is effected first by means of the tens gear Z (Fig. 17) of the gear set 4 by means of the racks D of the rack system B located within their reach. Consequently the four highest denominations of the product register P remain idle during the product total-taking, which is due to the fact that the capacity of the column totalizer was selected for values having only nine places. Step by step axial movement of the product mechanism P towards the left is controlled by the total taking mechanism in a manner not shown. In this way all denominations of the product mechanism P corresponding to the units order and orders of higher magnitude are shifted one by one past the racks-D (Fig. 17) and also past the tens order of the gear system 4, in order to be restored to zero by the total-taking process. Those denominations of the product mechanism which correspond to the tends and higher orders such as the hundreds, thousands, ten thousands positions and so forth, in case of the present product 4,5600" already stand at Zero. Consequently, K, by means of a suitable device, not shown, for preventing the registration of zeros before integers, the printing of zeros on the sheet is made impossible. With the step by step axial shift of the product mechanism, the paper carriage 8 is also letter spaced step by step towards the left until the units wheel of the column totalizer 98 arrives in calculating position. ,lt may be noted that during the previously mentioned step movement of the paper carriage 8, the roller 64' (Fig. 4) of the supporting member 96 is still rolling on the upper horizontal edge 92 of the rail 9U of the flap 66 and consequently the latter remains in the depressed posi- Owing to the above mentioned letter spacing travel of the paper carriage 8 and the product register P towards the left the particular gear of the product register P embodying the 4 of the product 4,5500 was also moved into a position opposite the rack D, that is, the tens gear Z of the gear set 4. Now, through the total-taking process, by means of the rack D and the tens gear Z of the gear set 4, the value 4 is entered from the said gear of the product mechanism into the units wheel of the column totalizer 98. Simultaneously the type lever prints the iigure 4 upon the sheet on the platen. During the return of the type lever a step of the paper carriage is started,` whereby the comma position of the column totalizer 98 is brought into its operative position. Owing to the fact that during the leftward step of the paper'carriage 8 also the product mechanism 'P is positively shifted leftward through one decimal place by the total-taking mechanism, ity will be found that at the completion of said step the column totalizer 98 with its comma place is in operative position and the product mechanism PLQ-not having a comma positionwith its gear representing the 5 of the tenths place of the product 4,5500 is in total-taking position, that is. opposite the rack D of the tens gear Z of the gear set 4.

Upon arrival of the comma place of the column totalizer 98 opposite the master wheel A, and as a result thereof, the comma rider 99 mounted on the bar causes its catch 99a to trip a distance skipping mechanism (not shown) for operation and initiate an additional step of movement of the paper carriage 3 effected in response to another revolution of the drive shaft, which also results in simultaneously shifting the product mechanism one step. Consequently the gear of the product mechanism P representing the of the hundredths order of the product 4,5500 is automatically brought into totaltaking position, that is, opposite the rack D of the tens gear Z of the gear set 4, without the 5 of the tenths order of the product 4,5500 having previously been set on 0 by totaltaking. Consequently, the tenths place after the comma of a product value would be skipped during total-taking. To avoid such faulty calculation the following device has been installed.

Comma skipping during product total-taking The automatic engagement of the total-taking mechanism of the bookkeeping machine after the calculation of the product, is effected by a positive depression of the total-taking key lever (Fig. 2) clockwise around its shaft |56. A bar |53 pivoted to the arm |51 of the key lever |55 is shifted rearwardly by the total taking key to cause a roller |59 of this bar |58 to wipe over` a cam face |60 at the lower end of a vertical slide |6| mounted to slide along the rear wall of the machine frame on pin and slot connections and moves said slide |6| upwards against the spring |62. A supporting member |64 is mounted to slide on the upper part of the slide |6| by means of a screw |63 (Fig. 4) and acted upon by a pressure spring |61 attached at one end to the 4pin of the screw |63 and at the other end to a pin |66 riveted into said supporting member and protruding through a longitudinal guiding slot |65 of the slide |6|. The supporting member |64 is also guided by a recess |68 of the supporting bridge 28.

The supporting member |64 participates in the upward movement of the slide |6| by means of the flexible connection |63, |61, |66 and thereby is moved into the path of a projection |69 of the slide 21 of the coupling system |8, 21, 46, which at this moment assumes the position shown in Fig. 17, the projection |69 being spaced from the left of the supporting member |64 by one step.

As soon as on product total-taking, the 4 of the product 4,5500 has been printed, the paper carriage shifts one step to the left and consequently the comma place of the column totalizer 98 is brought into operative position. The roller 94 of the member 96 (Figs. 4, r5 and 18) will also slide down the cam 93 of the rail 9|) of the flap 69. Consequently the members 66, 1|, 15 and 82 under action of spring' 11 are returned to rest position inthe direction of the arrow 19 and the edge of the crank 15 strikes against the rear edge 285 of the supporting bridge 28. Simultaneously the lock-catch 86 of the locking lever 62 is again moved out of the pathway of the edge s1 of the stop sa 'of the slide .21 so that now the coupling members yI8, 21, 46 are moved towards right by means of the spring `31. After having traversed a distance corresponding to one step of the paper carriage, the movement of the coupling members |8, 21, 46 towards right is stopped by the right lateral face of the projection |69 of the slide 21y striking against the left lateral face of the supporting member |64 (Fig. 18). Simultaneously the registering wheel 6` is moved by one step towards left by means of the gears |04, |95, |06, |09, H0, H8, so that thereafter the registering Wheel is in mesh with the rack F of the rack system B corresponding with the hundreds gear h of the gear set 4, as shown in Fig. 18.

It follows from the above that on skipping the comma place of the column totalizer 98 during the product total-taking, the paper carriage 8 and theV productmechanism P of the multiplying mechanism are moved by two steps, but the registering wheel 6, however, is moved one step only, so that the latter now faces the hundreds gear h, of the gear set 4 and serves to drive said gear h, for the purpose of total-taking from the product mechanism.

As explained above, the 5 of the tenths denomination of the product 4,5500 after skipping the comma place, registers with the hundreds place h, of the gear system 4, so that for the 'present the tenth denomination of the product "4,5500 is set to zero by total-taking. Thereupon the printing of the 5 startsa further step of the paper carriage 8 as well as of the product mechanism P, so that thereafter the 5 of the hundredths denomination of the product 4,5500 is moved into total-taking pick-up position, i. e.,

, in register with the hundreds place h, of the rack F of the rack systemB co-ordinated with the gear system 4, and is reset.

Subsequently, the thousandths and ten thousandths denomination of the product 4,5500 are cleared by total-taking. Since, however, these denominations in the present product 4,5500 already contain zeros, no clearing takes place by product total-taking. By means of a convenient cancelling mechanism, not shown or described, thevalues of the third and fourth orders to the right of the comma place are prevented from being printed. Neither can these values be included in the calculation of the product totalizer 98, since this column totalizer commands only two calculating orders to the right of the comma.

The product total-taking completed, the total-taking mechanism is also arrested automatically in a suitable manner since the key lever |55 (Fig. 2) is returned anti-clockwise into its normal position. Consequently the bar |58 is again moved towards the front, the roller |59 releasing the cam I6 of the slide |6l. The slide |6I and its supporting member |64 are now moved downwards by the spring |62 whilst the member |64 is, again placed out of reach of the projection |69 of the slide 21. Consequently the coupling system I8, 21, 46 is released and at this moment is snapped back into normal position in the direction of arrow 39 by means of the spring 31, the end 40 of the slide 21 striking against the rubber stop 4| (Fig. 4). The registering wheel 6 is also moved towards the left into normal position (Figs. 3k and 5) by means of the gears |04, |05, |06, |09, H0, ||I, H8. Simultaneously the products register P and the multiplier register C are suitably moved towards the right to normal position, according to Fig. 10.

As soon as the entries upon the line of the sheet have been completed, the paper carriage 8 is again moved to its right hand position by depressing the carriage return key |10 (Fig. l). During this movement of the paper carriage towards the right, the roller 94 (Fig. 4) of the supporting member 96 slides along the cam edge 93, 92 ofthe rail 90 of the flap 69, whereby the latter as wellas the members 1|", 115 and 82 are swung down in the opposite direction of the arrow 19 against the action of spring 11. Since, however, after a short while the catch lever 82 by means ofv its stop 86 strikes against the upper side'of the stop 88 of 'slide 21 of the coupling system I8, 21, 46, thecatch lever 82 does not participate' any more in the further movement of the members 69, 1|, 15, but only the spring 8| is tensioned.

During the subsequent movement towards the right ofthe ypaper carriage, the roller 94 again slides down the cam 9|, whereby the members 90, 69, 1|, 15, 32 are returned to normal position by the spring 11. i

On further sliding movement' of the paper ca'rriage to the right, the coupling member 22 by means of its cam edge 22a (Fig. 1) also bears upon the slant |1a of the hook `|1 of the pawl I8 the latter clockwise against the action of spring 51 which-pawl after the passage of the coupling member 22, returns again into its normal position. The same process is repeated as soon as during the sliding` movementof the carriage the coupling member |4 contacts with the catch |1 of the pawl IBL The locking pawl 46 is not affected thereby sinceA in the normal position of the Vcoupling system I8, 21, 46 it is kept outside of the path of movement of the coupling members I4 and 22by the controls 49, 50.
